To all whom it may concern:

Be it known that I, WILLIAM NrooL, a subject 'o the King of GreatBritain andlreland, and a resident of- Glasgow, Scotland, have inventedcertainnew and `useful improvements in Weatherproof and Like Fittingsfor Windows, o which the following is a specifica-- tion.

-This invention has reference to improvements in' sectional elevationshowing a easement window, with' my invention applied thereto, openinginwardly; Fig. 2 is a similar view showing the window opening outwardly; Figi 3 is a view similar to Figi l, showing a slightmodification; Fig. 4 is another modification; Fig. 5 represents asectional planview oi the sash and window 'frames with my inventionapplied thereto, and Figs. 6 and l" are perspective views oi portions oithe sill and the baille plates respectively. v,

My inventionis particularly applicable to easement windows which swingfrom-side hinges or to windows pivoted at a middle point in the top andbottom ssslies. In Figs. 1 to 4 l have shown my invention applied to thewindow sill A und the lower sashB of windows oi this character. .ln Fig.5 it is shown as applied to the side sashesoi easement windows at their.meeting point or to the side sash and th e upright of the window frameinwindows ol the character second above mentioned.

'ihe substance of my invention is formed in the in torlor'rking oftwoplates l0 and 11,'one secured to the sash B and one to the sill A. 1nmy preferred ferm ol construction (Fig. il) these plo-tes are formed todoubly interlock as illustrated, 5

` To carry out my purpose one edge of the sill plate 11 is formed Awitha hooked part l2, the upper arn 13 of which is-adaptcd to work under thelower tace o the sash 1l, while the other edge 11i is i'ormed with anoffset extension `which is clear of the sill. Attached to the lower iaceoi the sash is secured the sash plate 10.which by means of a similaroffset extcnsion16 and a hooked edge 17 cooperates with the sill plateto form a storm and dust prooi joint between the sill and the sash whenthe Window is closed. 1 make provision for the escape of any moisturethat may enter the space inclosed by these interlocking plates byint-lining the sill plate downwardly toward the outer face 18 ol thesill and 'opening therein drainage holes 1i) which permit the moistureto drain onto the ledge or the inclined outer face 18 of the sill. lnaddition, 1 provide arched baille plates 20 which arch over the holes 19and to some ex* tent impede the entrance oi wind through :hose holes. Oicourse openil'lgs 2l must he provided in the baille plates to permit theflow ol moisture to the holes 1,9. I have found it advantageous also toforni projecting ridges 22 on the faces oi' the plates which adjoin thesill and sash respectively and project into the surface thereof. Theseridges not only aid in resisting the torsional. strain to which theplates may be subjected in the open ing and closing oi the windows, butserve also as a further safeguard against rain and wind in ease thescrews 2f?, by which the plates are secured, become loosened and theplates become slightly separated from the suriaces to which they areattached. A v" Modifications of my invention may be variously devised.Thus in Fig. 1 the inner hook and cooperating offset projection areomitted. In Fig'. 2 the baille plate also is omitted and the sill plateinstead oi being inclined throughout its width, is merely 'arched'. Theouter half has thus the necessary incline and the plate is perfectlyeliectiveior drainage pur-poses since the moisture can entciouly overthe outer edge ol the sash plate and must drip upon the inclinementioned. In Fig. 4 drainage channels through the sill into which theholes in the sill plate open, are shown.

Where the plates are vertical at the junction ofthe vertical edges oitwo easement sashes (Fig. 5) there is ol' course no need of drainageholes and therefore oi baille plates. The plates merely doubly interlockas shown. i
